Occasionally when I try to start my car it wont start. It acts like its out of gas even with a full tank. When I turn my key on I can hear the fuel pump working so I dont beleive thats the problem. My fuel filter and air filters are new and in good condition. I have already elimatated plugs and plugwires. Eventhough its fuel injected when im trying to start it (while its being weird) sometimes if I hold the gas peddal just right I can get it to start, but that doesnt always work. Ive been told one of my oxegen sensors could be to blame, but I would like to know more.
